1. To protect work area, cover with newspaper.
2. Using a paper towel, apply a thin coat of petroleum jelly along the inner edges of the empty mold.
3. Mix the Outdoor Cement following the directions on the label. Wear a dust mask while mixing.
4. Pour cement slowly and evenly into mold; gently tap sides of mold to release any air bubbles in cement.
5. Do not move mold while the cement is drying. Wait for cement to harden. The cement will warm as it hardens.
6. Once it has cooled and set, remove the stone by turning mold over and lifting up the edges of the mold.
MOSAIC SHORTCUT: Use a preformed stepping stone from your garden center and skip instructions 1-6!
7. Enlarge the pattern below by 222%. Determine the center of the round stepping stone and align with the center of the pattern. Place carbon paper between the pattern and the surface of the stone and trace the pattern onto the stone.
8. Using the photo as a guide, arrange glass on the entire surface of the round stone, leaving approximately 1/8” gap between pieces and at the outer edge. Nip or break glass pieces with a Wheeled Glass Nipper to fit inside pattern outline.
9. When you are happy with the way your mosaic looks, lift each piece and apply a thin layer of glue to the back. Firmly press each piece onto the stone to match the pattern. Allow glue to dry according to the manufacturer’s instructions.
10. Reserve a few tablespoons of grout and set aside. Adding 1 tablespoon of water at a time to remaining grout, mix with craft stick or plastic spoon until the grout reaches “fudge-like” consistency. If it is too watery, add the reserved dry grout in small amounts until the consistency is correct.
11. Wearing a disposable glove spread the grout into all the nooks and crannies. Wait about 15 minutes for grout to set.
12. Gently wipe away the excess grout using a paper towel taking care not to pull grout out of tile spaces. It is very important to remove any grout from the tile surface before grout is completely dry.
13. Use a soft cloth to buff the tiles to a clean shine. 14. Allow 24 hours for the mosaic piece to dry.
